摘要
随着电压等级的升高,直接验电方式越来越难以满足高压输电系统发展的需求。该文提出了一种非接触式特高压综合验电技术,即采用灵敏度极高,检测原理不同的电场传感器和日盲型紫外探头,在用激光对待测点测距定位后,对传输线、开关等高压设备的电场强度和电晕放电中的紫外脉冲分别进行实施检测,以确定线路和设备的带电状态。基于该技术研发了一种新型特高压综合验电仪。
The method of directly electrical inspecting will not meet the development of high voltage transmission line with the improvement of voltage level.The paper proposes a novel method of non-con-tact extreme high voltage synthetic electrical inspection based on electric field sensors and solar-blind ultraviolet detectors with higher sensitivity and different detection theories.The proposed method deter-mines the charged state of line and equipment by detecting the electric field intensity of high-voltage equipment ( transmission line and switches, etc.) and corona-discharging ultraviolet impulse after range-based localizing of detecting spot using laser.A novel extreme high voltage synthetic electrical inspec-tion equipment is developed based on the technique.
